Series and Parallel Circuits | Electricity | Physics | FuseSchool

The video tutorial explains the differences between series and parallel circuits, focusing on how components are connected and how current flows. It covers the concepts of voltage, current, and resistance, including how to measure them using voltmeters and ammeters. The tutorial also provides rules for calculating total voltage, current, and resistance in both series and parallel circuits, with practical examples and exercises to apply these rules. The video concludes with a detailed explanation of calculating resistance in parallel circuits using specific formulas.

In a series circuit, how are the components connected?

• In a loop

• End to end

• Randomly

• Side by side

What does a voltmeter measure in a circuit?

• Power in watts

• Voltage in volts

• Resistance in ohms

• Current in amps

How is electric current measured?

• In watts using a wattmeter

• In amps using an ammeter

• In ohms using a resistor

• In volts using a voltmeter

What happens to the total resistance when resistors are connected in parallel?

• It remains the same

• It decreases

• It doubles

• It increases

If two resistors of 3 ohms each are connected in series, what is their total resistance?

• 1.5 ohms

• 3 ohms

• 6 ohms

• 9 ohms
